Label=(label-name-list)

    Specifies the 1- to 6-character string with which the volumes
    of the backup file are to be labeled. The Label qualifier is
    applicable only to tape volumes. You must specify one or more
    label names when you use the Label qualifier.

    You can specify a list of tape labels for multiple tapes. If you
    list multiple tape label names, separate the names with commas
    and enclose the list of names within parentheses.

    If you do not specify the Label (or Accept_Label) qualifier,
    Oracle RMU labels the first tape used for a backup operation
    with the first 6 characters of the backup file name. Subsequent
    default labels are the first 4 characters of the backup file name
    appended with a sequential number. For example, if your backup
    file is my_backup.rbf, the default tape labels are my_b, my_b01,
    my_b02, and so on.

    When you reuse tapes, Oracle RMU compares the label currently
    on the tape to the label or labels you specify with the Label
    qualifier. If there is a mismatch between the existing label and
    a label you specify, Oracle RMU sends a message to the operator
    asking if the mismatch is acceptable (unless you also specify the
    Accept_Labels qualifier).

    If desired, you can explicitly specify the list of tape labels
    for multiple tapes. If you list multiple tape label names,
    separate the names with commas and enclose the list of names
    within parentheses. If you are reusing tapes be certain that
    you load the tapes so that the label Oracle RMU expects and the
    label on each tape will match, or be prepared for a high level of
    operator intervention.

    If you specify fewer labels than are needed, Oracle RMU generates
    labels based on the format you have specified. For example, if
    you specify Label=TAPE01, Oracle RMU labels subsequent tapes as
    TAPE02, TAPE03, and so on up to TAPE99. Thus, many volumes can
    be preloaded in the cartridge stacker of a tape drive. The order
    is not important because Oracle RMU relabels the volumes. An
    unattended backup operation is more likely to be successful if
    all the tapes used do not have to be mounted in a specific order.

    Once the backup operation is complete, externally mark the tapes
    with the appropriate label so that the order can be maintained
    for the restore operation. Be particularly careful if you are
    allowing Oracle RMU to implicitly label second and subsequent
    tapes and you are performing an unattended backup operation.
    Remove the tapes from the drives in the order in which they
    were written. Apply labels to the volumes following the logic
    of implicit labeling (for example, TAPE02, TAPE03, and so on).

    Oracle Corporation recommends you use the Journal qualifier when
    you employ implicit labeling in a multidrive, unattended backup
    operation. The journal file records the volume labels that were
    written to each tape drive. The order in which the labels were
    written is preserved in the journal. Use the RMU Dump Backup
    command to display a listing of the volumes written by each tape
    drive.

    You can use an indirect file reference with the Label qualifier.
    See the Indirect-command-files help entry for more information.
    See How Tapes are Relabeled During a Backup Operation in the
    Usage_Notes help entry under this command for a summary of which
    labels are applied under a variety of circumstances.
